boat trailer tongue weight setup calculator
Boat Trailer Tongue Weight Setup Calculator
A practical trailer target is often 10%-15% of loaded trailer weight on the tongue. Too little tongue weight increases sway risk; too much can overload hitch or tow-vehicle payload.
Formula
(boat wet weight + trailer + fuel + gear) x target tongue-weight percentage
Source-backed rate table
Every source row includes a source URL and date context. Where a national rate does not exist, the page uses a transparent estimate range and labels the source type.

Region difference table
Region multipliers keep the tool useful without pretending that one national marina price exists.
| Region | Multiplier | Adjustment reason |
|---|---|---|
| Northeast | 1.18x | Higher yard labor, strong winterization season, and dense marina markets. |
| Mid-Atlantic | 1.08x | Moderate winterization and coastal yard pricing. |
| Southeast | 0.95x | Lower winter storage demand, but high detailing and saltwater maintenance needs. |
| Great Lakes | 1.14x | Strong winter storage, shrink-wrap, haul-out, and seasonal service demand. |
| Gulf Coast | 1.02x | Saltwater service exposure with less cold-weather storage pressure. |
| Pacific | 1.16x | Higher labor and yard access costs in major coastal metros. |
| Inland lakes | 0.90x | Usually lower storage and labor costs outside coastal marina markets. |
Comparison: calculator vs. quote shortcuts
| Approach | What you get | Weakness |
|---|---|---|
| BoatCostCalc | Formula, source table, region factor, worksheet | Planning range, not a provider quote |
| Single marina PDF | Real provider price for one market | Hard to compare across services and regions |
| Forum quote | Anecdotal owner experience | Unknown scope, date, fees, and boat configuration |
FAQ
Is this an exact provider quote?
No. It is a planning range built from public source rows. Use it to compare quoted scope, not to replace a marina estimate.
Why do the estimates use ranges?
Boat service prices move with region, access, boat type, add-ons, and yard fees. A range is more honest than false precision.
What should I confirm with the provider?
Confirm taxes, environmental fees, haul-out, travel, add-ons, storage dates, bundled services, and whether the quote uses LOA, beam, per-engine, or per-seat pricing.
